The Next It Sandwich? Sea Urchin

Chefs have proclaimed pork their favorite sandwich filling, creating everything from new takes on banh mi to messy pork-belly sliders. But recently I've been spotting uni (sea urchin) on sandwiches all around New York City. Uni-obsessed chef Michael White is serving sea-urchin-and-lardo crostini at his new seafood restaurant, Marea. Chef George Mendes has created a stellar sea urchin toast with cauliflower cream for his menu at the recently opened Aldea. And the Chelsea tapas spot El Quinto Pino does a clever sea urchin panino.
